Chicago Cubs right-hander Yu Darvish has undergone arthroscopic surgery on his right elbow to clean out loose debris.
Darvish was declared out for the season last month after an MRI revealed a stress reaction in the elbow. He recently visited orthopedic surgeon James Andrews for a second opinion and the surgery was recommended.
The team announced that the procedure, termed a debridement, was performed on Wednesday by Texas Rangers physician Keith Meister, who has a history with Darvish.
The Cubs said Darvish would be ready for spring training.
